A work ship is a type of ship whose purpose is primarily to carry out work on or from the water. They are therefore not primarily used for transport . Excavation barges , in which the excavated material is transported for dumping , are an exception . Dredging barges can fold away the bottom so that the dredged material can be folded up (sink to the ground).

The workboats can be, for example, floating cranes , dredgers , lightships , pilot boats , tenders , research vessels , drilling vessels , cable layers , pipe fitters , icebreakers or be a survey ship. They are particularly marked in the rule ( lights- and fly its flag ) to inform the shipping industry.

The largest work ship in the world is the Pioneering Spirit , which was measured with a gross tonnage of 403,342.

A special type of work vessel are the deep-sea work vessels ( English Deepwater Construction Vessels , DCV for short), which are used to erect or dismantle offshore structures or to lay pipelines . They are usually equipped with one or more large cranes (e.g. a lifting capacity in tandem lift up to 14,200 tons), special equipment, e.g. a J-Lay or S-Lay tower for laying pipelines, and / or diving robots, so-called Remotely Operated Vehicles (ROVs).
